The basic idea...

"The basic idea behind open source is very simple. When programmers on
the Internet can read, redistribute, and modify the source for a piece
of software, it evolves. People improve it, people adapt it, people
fix bugs. And this can happen at a speed that, if one is used to the
slow pace of conventional software development, seems astonishing...
...The Open Source pages exist to make this case to the commercial world." - Introduction to Open Source - www.opensource.org

* Bitcoin Deck Wallet

DeckWallet is a simple application that allows you to generate up to 52 bitcoin addresses by entering the order of a deck of cards plus an optional password.

About security- Completely offline, it does not requires any permissions.- You don't need to type anything (except the optional password), so it's not vulnerable to keyboard malware.- Protection against typos and miss-entered cards.- 2FA: Option to enter a password (or more than one to create secondary wallets) besides the deck itself.- Obscurity: An attacker won't know there are bitcoins in that deck, even if they find it.

Instructions- Shuffle a deck of cards 7 times.- Select the number of cards to use. 52 is recommended.- Enter every card on the app.- Optionally enter a password you won't forget (it's not possible to recover it!).- Touch "Go!" to generate up to 52 bitcoin addresses.- Optionally, copy the order of the cards into another deck, as backup.- Double-check your deck wallet: Touch the 'Check' icon and re-enter the same password and card order.- After checking it, send some bitcoins to your deck wallet and store your deck of cards in a safe place.
